Patented Aug. 23, 1932 UNITE STATES PATENT? OFFICE ALBERT L. ABBOTT, OFCANTON, OHIO, ASSIGNOR TO DIEBOLD SAFE & LOCK COMPANY, OF CANTON, OHIO,A CORPORATION OF OHIO SAFE Application led October 8, 1929. Serial No.398,157.

My invention relates to safes, and more particularly to safes made ofsheet metal and heat resisting material, and adapted for the protectionof valuables, documents, records, and the like, against the usualhazards and particularly against the hazards of fires, ex plosions andof combined fires and explosions.

Safes for this purpose should be built to withstand and endure with asubstantial margin of safety, separately or simultaneously, the hazardsof impact, crushing loads, and falls, and of long periods of intenseheat.

Considerable difculty has been encountered in making a structure havingthe capacity to withstand all of these hazards.

Safes have been made including an inner main frame made of structuralshapes surrounding and maintaining a compartment in which are placed thevaluables, documents, records, and the like to be protected, the mainframe and compartment being themselves surrounded by a combined heat andcompression resisting monolithic shell, and the compartment, main frameand monolithic shell all being surrounded by an external sheet metalcase.

Such a safe structure is adequate from the standpoint of strength, butis relatively costly to manufacture. As aforesaid, the several partsthereof include two classes of materials, structural shapes and sheetmetal, thus necessitating for each class, the special equipment andspecial labor necessary for working that class of material.

The objects of the present improvements include the provision of a safewhich, except for hardware and fittings, may be made entirely of sheetmetal and heat resisting material, and which at the same time shall meetthe requirements as to strength and resistance to fire, heat andexplosion, whereby a single class of material and labor may be used,less weight of material are required, and manufacturing economiesthereby effected.

These and other objects are attained by the use of an inside compartmentin which are placed the valuables, documents, records,

and the like to be protected, the compartment walls being preferablymade of panels comprising spaced metal sheets and the metal sheets atsides of each panel being formed and positioned for overlapping with themetal sheets at sides of the other panels to form at the corners of thecompartment a main structural frame the members of which are preferablyW-shaped in cross section and are laminated by reason of the overlappingof the metal sheets, and are positioned with respect to the externalcase in such manner as to permit the use of a maximum amount of heat andfire resisting material in the monolithic shell at the corners.

A preferred embodiment of the invention is illustrated in theaccompanying drawings forming part hereof, in which Figure 1 is afragmentary vertical cross section of one of the improved safes, as online 1-1, Fig. 2;

Fig. 2, a fragmentary horizontal cross section of the same, as on line2-2, Fig. 1; and

Fig. 3, a fragmentary perspective view illustrating the manner ofoverlapping and joining the panel sides to form the laminated mainframe.

Similar numerals refer to similar parts throughout the several views.

The improved safe indicated generally at 10, includes panels forming anovel fivewalled inner compartment indicated generally at 11, afive-walled monolithic heat and fire resisting shell indicated generallyat 12, the shell being provided with tension reinforcing means indicatedgenerally at 13, and the compartment and shell being enclosed in anexternal five-walled interlocking case indicated generally at 14.

A door frame indicated generally at 15 connects the opening of the innercompartment 11 with the opening of the outer case 14, and forms aclosure for the outer end of the monolithic shell 13.

A door indicated generally at 16 is mounted at one side by hinges 17upon the outer case, and provides a closure tting in the open sixthsides of the case and compartment.

The door preferably includes an outer shell ii @mit 18 of metal sheets,the interior of which is iilled with heat resisting material 19 andtension reinforcing 20.
